+--
+-- > import XMonad.Layout.DwmStyle
+--
+-- Then edit your @layoutHook@ by adding the DwmStyle decoration to
+-- your layout:
+--
+-- > myL = dwmStyle shrinkText defaultDwmStyleConfig (layoutHook defaultConfig)
+-- > main = xmonad defaultConfig { layoutHook = myL }
+--
+-- For more detailed instructions on editing the layoutHook see:
+--
+-- "XMonad.Doc.Extending#Editing_the_layout_hook"
+--
+-- You can also edit the default configuration options.
+--
+-- > myDWConfig = defaultDwmStyleConfig { inactiveBorderColor = "red"

+-- > myL = dwmStyle shrinkText myDWConfig (layoutHook defaultConfig)
